Technical Abstract: The mutant was induced in the tall Arkansas rice cultivar Drew (PI 596758) in order to quickly obtain semidwarfism in adapted germplasm. This recessively inherited mutant, which is 25 cm shorter than its parent, provides breeding material adapted to the southern U.S. And similar climatic areas. The mutant provides a nonallelic semidwarfing source should genetic vulnerability problems arise from widespread use of sd1.
